  2. Squash Preparation: Slice spaghetti squash lengthwise, carefully removing seeds and inner pulp with a spoon, then thoroughly coat with olive oil and season with salt and black pepper.
  3. Initial Roasting: Position squash cut-side down on prepared baking sheet, allowing caramelization and flavor development during roasting, bake for 30-40 minutes until tender and easily pierced.
  4. Strand Creation: After cooling slightly, use a fork to gently scrape squash interior, creating spaghetti-like strands and transferring to a mixing bowl.
